lM PROVE'M ENT IN CARBURETERS.

Specification forming part of Letters Patent No.

215,072, dated May 6, 1879; application filed February: 21, 1879.

To all whom 'it may concern:

Be it known that I, FRANK G. SGHUGHARD, of Brooklyn, county of .Kings,and State of: New York, have invented certain newand useful Improvementsin Garbureters, of which the following is a specification.

In the accompanying drawings, Figure 1' represents a front elevation,with part broken out, of my improved carburetor; Fig. 2, a verticaltransverse section of the same on line mac, Fig. 1; and Fig. 3 is adetail section of the air-drum.

Similar letters of reference indicate corresponding parts.

The object of this invention is to'furnish an improved gas apparatus inwhich theair is supplied to the carbureting-drum iuuniform and reliablemanner; and the invention consists of a gas-machine in which theair-pump ,is constructed of radial wings, which extend alternately fromthe circumference at one side of the drum to the center shaftattheotlier" side of the'drum. :These triangularfiwings of the drumhave'ang'ular'and overlapping extensions, which .form 'the side walls,and admit the water to pass in at one side and force out the air at theopposite side.

The air-drum has anannular chamber encircling the air-entrance pipe ofthe pumpcasing, said chamber a regulating-opening at one point of thecircumference; as will be more fully described, and finally pointed outin the claims. 1

Referring to the drawings, A represents the outer casing of my improvedgas apparatus, which contains in its broader base the reservoir B forthe gasoline or other liquid hydrocarbon, and carries at the top partthe airpump 0. Between the casings of the reservoir B and of theair-pump O is arranged a jet-pipe, D, which is connected by a pipe, a,with stop-cock to the gas-main leading from the reservoir B to thedistributing-pipes, The jet-pipe D is made arc-shaped, so as to beconcentric, or nearly so, to the cylindrical casing of the air-pump;When the stop-cock of the connecting-pipe is opened, the gas passesthrough the perforations of the pipe D, and may be lighted byintroducing a light through an opening, I), of the casing A. Theheatingjets arelighted whenever the water in the air-pump is frozen upin cold weather, the heat of the same melting the ice and setting thedrum quickly and conveniently into working order without the annoyinginterruptions 'caused'by the freezing up of the air-pumps in thegas-machines at present in use. In large machines two or more jet-pipesmay be arranged at suitable distances from each other, so that theheating of the water and the melting of the ice may be quicklyaccomplished.

. ;As soon as the air-pump begins to work properly the jets areextinguished by closing the stop-cock, though in very cold weather theymay be left burning, so as to insure theregular and reliable working ofthe air pump without any danger of the freezing up of the Water.

The air-pump O is operated in the usual ,manner' by a weight andtransmitting gear applied to the shaft of the air-drum, the weight'being hoisted by a hand-crank and Winding-up mechanism. The air-pump isconnected by a pipe,0l, with the reservoir B, the pipe (1 extending fromthe upper part of the pump-casing to a point near the shaft of thecarbureting-drum B. The water is filled; in through a hole at the top ofthe pump-casing, and drawn offthrough a faucet near the bottom. The

shaft 0 of the air-drum O revolves in center bearings of one side wallof the pump-casing and in bearings of a central air-tube, f, of theopposite side wall. An upwardly-extending tube, f, of the air-tubeconducts the air to the interior of the air-drum O.

The air-drum O is constructedof an exterior cylinder with interiorradial rings g, which latter are not extended acrosswthe entire width ofthe drum, but made of triangular shape, so that their outer edge runsdiagonally from the outer cylinder to the shaft of the drum. These whichthe water enters at one side, while the air is forced out at the otherside.

The cylinder of the air'drum is closed at one side, so as to form anannular chamber, 0 that extends around the air-inlet tube f. The air andwater pass into the drum at this side, the air being forced out at theopposite side and finally compelled to pass to the connecting-pipe d.

The chamber (J has at one point of its circumference a triangularexit-aperture, h, as shown in Figs. 2 and 3, which passes alternatelythrough the water and air-space of the pump, and serves as a regulatorof the water-level in the drum, as otherwise the water would becontinually forced toward the open side of the drum. The openingrestores the proper level of the water and secures the more uniformoperation of the drum.

The triangular shape of the wings and their arrangement at alternatesides of the air-drum causes their gradual and successive entrance intothe water of the air-pump, and thereby the uniform and reliable forcingout of the air, so as to produce a current of constant strength in placeof the unequal and interrupted current obtained by the common air-pumps.The overlapping extensions of the wings facilitate the entrance of thewater and the exit of the air compressed by the alternate dipping of theradial wings into the water, and supply thereby the great desiderat umin carbureters--namely, a continuous and constant current of air.

The air passes from the pump to the reservoir B, and is there forcedthrough the carbnreting-drum B, which is made of a sheetmetal cylinderwith perforated side walls and of a filling of small pieces of sponge orother porous or fibrous material that is capable of absorbing thehydrocarbon and exposing it in minutely-divided state to the evaporatingaction of the air.

The drum B is revolved by belt-and-pulley connection with the shaft ofthe air-drum. The outer cylinder of the drum has a number of radialpaddles or stirrers, i, which pass close to the bottom of the reservoirand serve to agitate the liquid hydrocarbon and to prevent the settlingof the heavier parts to the bottom of the reservoir. This mixing of thelighter and heavier parts by the paddles furnishes a uniform quality ofhydrocarbon, and therefore a more uniform quality of gas through out,which is not the case in the common machines, in which the lighter partsare first taken up by the drum and evaporated, while the heavier partshave time to settle.

The earbureting-machine is of compact and reliable construction, andovercomes to a considerable extent the objectionable feature of thegas-machines at present in use.

I am aware that heating devices for the water of the air-drum have beenemployed heretofore, also devices for properly stirring up thehydrocarbon, and Itherefore do not claim the same.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patcut- 1. In a carbureting-machine, an air-drum constructedof an exterior cylinder and interior radial wings of triangular shape,that extend alternately from opposite sides to the center shaft,substantially as set forth.

2. In a carburetingmachine, an air-drum made of an exterior cylinder andof interior radial wings of triangular shape, that extend alternatelyfrom opposite sides to the center shaft and have overlapping extensionsforming the side walls, substantially as described.

3. In a carbureting-maehine, a revolving airdrum, 0', provided with anannular chamber, 0 at one side, said chamber having aregulating-aperture, h, at its circumference, in combination with theinclosing-casing of the pump and with the air-inlet tube ff,substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two witnesses this 18th day of February, 1879.
